VOCSens’ EnviCam-30 is ultra-low-power multi-gas microsensor with self-calibration capabilities for deployments across many applications lasting up to 10 years. The device comes in a 10 x 5 x 0.9 mm LGA package and was designed to supply data for IoT and Industry 4.0 solutions.
The EnviCam-30 is supplied by 1.8 V with VDDIO between 1.8 V and 3.3 V. Current on and current off are <1 mA and <10 µA respectively. Power consumption is <50 µW continuously at one measurement per second, and the device has an output of 0.1 to 100 kHz.
VOCSens’ patented CMOSEnvi™technology enables high selectivity of chemical compounds for measurement. At the time of this writing, the EnviCam-30 is capable of measuring:
-> Ammonia (NH3) @ 0.2-200 ppm
-> Carbon monoxide (CO) @ 1-2000 ppm
-> Nitrogen dioxide (NO2) @ 0.025-200 ppm
-> Formaldehyde (HCHO) @ 0.1-20 ppm
-> Acetaldehyde (CH3CHO) @ 0.1-20 ppm
Methane, carbon dioxide, and hydrogen sulphide measurement capabilities should be made available soon, and additional sensing for BTEX, ethylene oxide, ethylene, sulphur dioxide, hydrogen, and acetone is under development. Extended measurement range and dedicated developments are available by request.
VOCSens provides ample support for integration of the EnviCam-30 into an end device, including C firmware libraries to control the multi-gas microsensor and to integrate it into your embedded software application. Preliminary information on an evaluation kit is available here, and this kit allows the user to swap out the chip and follow VOCSens’ product development. A second, plug-and-play kit will be widely available soon, and this features a finished chip for immediate testing before integration into your design. In this eventuality, any application through ipXchange will be to enter consultation with VOCSens to determine which evaluation method is best suitable for your project and its development timeline.
